So when the stars are extinguished.
Thus, when the stars are put out
When the stars are extinguished
So when the stars are made to disappear
So when/if the stars/planets were eliminated/effaced
When the stars become dark
So when the lights of the stars are put out
So when the stars are made to lose their light
Then when the light of the stars will be extinguished
So when the small stars will be made to lose their light
Then when the stars lose their lights
